*UCI TRANSFER* Does getting a financial letter in the mail basically mean you got accepted?

Hi everyone,
Recently applied to UCI (and other UC’s) as a science major. I know acceptances don’t come out till April 1-30th but there is a rumor going around that if you get a letter in the mail asking for financial information that it’s a given you got accepted. One of my friends received one of those letters last week, and I have not. Should I lose hope? Does everyone get that letter as a hint of acceptance?
